Automate a security incident response workflow with domain delegation

Automate key steps in incident response by scanning, flagging, and remediating risky accounts or files, using a delegated service account.

The problem

Manual incident response is slow and error-prone, especially when accounts or documents must be locked down quickly. A delegated service account can automate detection and mitigation, but only if it can reliably traverse the necessary resources and take action without human delay.

How it works

  1. Detect incident triggers via webhook, SIEM, or periodic polling.
  2. Enumerate affected users or files using Admin SDK directory and Drive API queries.
  3. Apply containment: suspend accounts, revoke sessions, or restrict file sharing as appropriate.
  4. Log every change with the affected resource identifiers and timestamps.
  5. Notify a human operator with a summary and links to all actions taken.

What changes

Critical response steps (account lockdown, file permissions change) are enacted within seconds and fully logged, reducing impact window and audit risk.

The trap in this one. Admin SDK user suspension and Drive API permission changes are not always atomic. If you suspend a user and then immediately try to alter their file permissions, you can hit a propagation delay: files may not surface as owned by a suspended user for several minutes. Automations that assume instant consistency will silently miss files in the first pass, leaving sensitive data exposed until a follow-up sweep.

Questions people ask

Can I rely on a single API call to enumerate all a user's files?

No. Changes to account state can take time to propagate, and file ownership queries may lag behind user suspension. Always re-scan after a delay.

Does revoking sessions log out users instantly?

Session revocation is quick but not always immediate. Some mobile or offline clients may hold active tokens for several minutes before being forced out.

Want this built?

This is a pattern we run in production. We will set up the delegation and build this on top of it — $500 per hour, most of it working the same day.
